CROSS-REFERENCE TO A RELATED APPLICATION

This application claims priority to European Community Plant VarietyOffice (CPVO) Plant Breeder's Rights Application No. 2021/1906 filed onJul. 21, 2021, under 35 U.S.C. 119(f), the entire contents of which isincorporated by reference herein. There have been no offers for saleanywhere in the world prior to the effective filing date of thisApplication and no accessibility to one of ordinary skill in the artcould have been derived from the printed plant breeder's rightsdocuments.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Bidensferulifolia plant, botanically known as Bidens ferulifolia ‘FSK17S28’and will be referred to hereinafter by its cultivar name, ‘FSK17S28’.The new cultivar of Bidens is an evergreen perennial grown for landscapeand container use.

The new cultivar was derived from a controlled breeding programconducted by the Inventor in Katsuta-Gun, Okayama-Pref., Nagi-chioGyoho, Japan. The new cultivar arose from a cross made in June of 2013between an unnamed and unpatented proprietary plants from the Inventor'sbreeding program; reference no. F1205 as the female parent and ref no.F1207 as the male parent. The Inventor selected ‘FSK17S28’ in October of2014 as a single unique plant amongst the seedlings that resulted fromthe above cross.

Asexual propagation of the new cultivar was first accomplished by stemcuttings in March of 2015 by the Inventor in Katsuta-Gun, Okayama-Pref.,Nagi-chio Gyoho, Japan. Asexual propagation by stem cuttings hasdetermined the characteristics of the new cultivar are stable andreproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined tobe the characteristics of the new cultivar. These attributes incombination distinguish ‘FSK17S28’ as a unique cultivar of Bidens.

-   -   1. ‘FSK17S28’ exhibits medium sized inflorescences.    -   2. ‘FSK17S28’ exhibits inflorescences with ray floret colors        that deep red in color.    -   3. ‘FSK17S28’ exhibits a moderately vigorous plant habit.    -   4. ‘FSK17S28’ exhibits a mounding to semi-trailing plant habit.

The female parent differs from ‘FSK17S28’ in having largerinflorescences with ray florets that are deeper red in color and a morevigorous growth habit. The male parent differs from ‘FSK17S28’ in havinga slightly larger inflorescences size with ray florets that areorange-red in color, a more vigorous growth habit, and an upright planthabit. ‘FSK17S28’ can also be compared to the Bidens cultivar ‘GoldenEmpire’ (not patented). ‘Golden Empire’ differs from ‘FSK17S28’ inhaving a mounding to upright plant habit and inflorescences with rayflorets that are yellow in color.
